 684 Signals and Windows
 685 ===================
 686 The SIGHUP signal does not exist on Windows and does not need to be handled.
 687
 688 Windows handles SIGFPE and SIGSEGV signals as expected.
 689
 690 Cntl+C interrupts (mapped to SIGINT by Windows' POSIX compatability layer)
 691 cause a new thread to be spawned. This may well result in unexpected
 692 behaviour by the single-threaded LyX.
 693
 694 SIGTERM signals will come only from another process actually sending
 695 that signal using 'raise' in Windows' POSIX compatability layer. It will
 696 not come from the general "terminate process" methods that everyone
 697 actually uses (and which can't be trapped). Killing an app 'politely' on
 698 Windows involves first sending a WM_CLOSE message, something that is
 699 caught already by the Qt frontend.

 702
